Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19650, here are decompositions:

  • 41 + 19609 = 19650
  • 47 + 19603 = 19650
  • 53 + 19597 = 19650
  • 67 + 19583 = 19650
  • 73 + 19577 = 19650
  • 79 + 19571 = 19650
  • 97 + 19553 = 19650
  • 107 + 19543 = 19650

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19650 first appears in π at position 19,282 of the decimal expansion (the 19,282ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
